TOBACCO' PIPE.

Application filed May 2i, 1923. Serial No. 640,306.

To all whom it may cio/noemt' Y Be it known that we, .IULiUsjBAUnn and CHAiiLns i Konuiesnnemg citizens ofV the United States, residing, respectively, at Chi-v cago, inthe county of Cook and State oit Illinois, and at Chicago, .in the countynof Cook and State oi Illinois, have jointly invented certain new and usefulv` Improve` ments in Tobacco Pipes, of which the tol-V lowing is a specification. 1 Y This `invention relates to tobacco pipes. One object or" the invention isy to provide other suitable metal, particularly in the inatter of avoiding heating oit' the exteriorusurf face ot the pipeV to a degree which would' render it uncomfortable -to'handle and also in the matter of rendering the construction suiiiciently light to adapt it to be held inthe smokers mouth ywithout inconvenience.A In realizing this object, the 'pipe is made with a bowl to contain'thecharge of tobacco and a surrounding body wallv through which the pipe is handled', which, while largely supported by the bowl issoconnected there- Y with and spaced therefrom vthat transmis sion ot heat, whether vby conduction 'or by radiation across the intervening space, is reduced well below that which 'is dissipated by radiation from the body ,'wall; the con-` nection between the shell 'or surrounding wall and the bowl being limited to ythe" topKV margin of theA bowl and beingo greatly reducedHsectio-n so thatthe heat conducting capacity between the vbowl. and the shell is yvery small, and the` body wall being so upper margin of the `bowl and `withthe base, in order to still further reduce the sec-v tional area of the heat is conducted. Y

Another object of the inventionvis'to render a pipe, constructed Vgenerallyv asl a'ioiesaid, selifrighting, -so that if laid on one metal through which the side'it will assume an upright position. To this end, the body wall is made substan-v tiallyvspheiical, and the base with litsv stemreceiving barrel, and upon which the bowl is mounted andto which, in the preferred `embodiment the said wall is united, is

merged'withthe spherical wall at the'lower pole roi the sphere and is made sufficiently heavier than the bowl to cause it toV actas a. counterweight'.

The invention vconsists in the "features of novelty `e:\.einplified in the illustrative embodiments of the invention hereinafter de-y scribed, 'aiid particularly pointedout in thel claims'. y.

y In the accompanyingdrawings- Fie-ure l is a vertical central section of one ei'nboidiinentk of the pipe, the planeof' section being coincident with. the axis of the stein-receiving barrel.

Figure 2 is a vertical central section a plane at right angles to Figure l.

Figure 3 is an end elevation as seen from the 'right of' Figure l.

Figures 4 and 5 are views similar to Fig.- ures l and' 2-showing ay inodified'construc tion. i

Figures 6 and 7 are, respectively, a top plan view and a bottomplan viewof the embodiment shown 'in Figures 4 and 5; and

v Figure 8 is a vertical section showing a furthery modification. y A f Referring to Figures l to 7, l represents a base` constructed with a smoke chamber 2 and a. stem barrel 3 in` communication witln said chamber.k 4 represents a bowl iitted to the base 1 over the smoke chamber 2f,V in any suitable manner that will cause the base' to remain in assembled relation, such, for instance, as by means of screw threads 5. yThe bowl 4 has upon, its lower end, within the smoke chainber', a reduced end 6' with a diametric bore that intersects the lower end'y of the bowl cavity and provides smoke ducts 7 through which the cavity of the bowl communicates with the smoke Chamber 2.

lSupported upon the upper-'margin 4 of the bowl 4, depending theretroinand surrounding the bowl with a substantial intervening space 8, is a wall 9 that extends downwardly beyond the bottom o'the bowl and provides a relatively cool while in use. l/Vall 9 has no directconnection with the bowl 4 except atthe top mar-- gin l4a, where the section oi the connecting I io5 f,

body` through p which the pipe may be comfortably handled n wall is such as to greatly reduce the heat transmitted by conduction. stitutes the support for the wall or a substantial portion thereof, the bowl being in turn supported upon and in upstanding relation to the base l. Wall 9 may be, and preferably is, further supported by uniting t with the base l at the lower margin ot the wall, well below the bottom of the bowl ll, except at the portion of the wall 9 which is intersected by the stem-barrel 3.

Preferably the general form of the body of the pipe afforded by the surrounding wall is spherical orspheroidal, with the lower longitudinal line of the barrel 3 coincident with the lower pole of the sphere and eX- tending tangentially therefrom so that the center ofl gravityot` the pipe as a whole is below the center of the sphere and the pipe is rendered seltsustaining, in an upright position and selirighting in case it should )e laid upon its side, the circular section ot the body in a plane transverse to the axis of the stemreceiving barrel constituting the surface uponv which the pipe rolls under the overfbalancing load of the tangentially united base and stem barrel; and the barrel bracing it against tipping in a vertical longitudinal plane.

Referring particularly to igures 4 to 7, the union of the spheroidal wall 9with the top margin la of the bowl l may be greatly reduced in conductive sectionv by providing` a circularseries-of apertures l0 which reduce the se arating connection of the wall 9 at the bow l 4 to narrow necks ll ot any suitable"number.: Similarly, the connection of the lower marginof the wall 9 with the base l may be lreduced in conductive area by means of a slot l2 of anyvsuitable design,

(herein Ishown as horse-shoe shape) conforming closely to the contour of the base l except Y where interrupted by the stem barrel 3,.

l/Vhen the bowl 4t is made removable from the basel and provided, oi course, the wall 9 is united with the base in addition to being ksupported on the bowl,l said wall is divided equatorially as at i3 or on some other equivalent lines, and this permits the separation of the bowl from the base and thus gives access to the smoke chamber 2 for cleaning same.

Some of the advantages of the invention can be realized, at least to a measurable degree, by the forml of construction such as shown in Figure 8, in which the bowl 4X and the base 1X constitute an integral structure with the smoke chamber 2X yformed therein by coring or otherwise, and serving as well to receive the stem 14. ln this torni of all metallic spaced radiating wall pipe, wall 9X extends integrally from the upper margin i-a of the bowl, first outwardly to develop a substantial space 8X, and then down- Tlie bowl conwardly to a point below the bottom of thel bowl where it terminates in completely spaced relation to the base 1X.

l. A tobacco pipe, comprising a substantially spherical hollow body divided equa-V .torially into upper andlower substantially member and in communication with said stem socket, and a bowl extending down wardly within and supporting the upper body member; said bowl being releasably united to the base and holding the two body members together.

2. ln .a tobacco pipe, a base constri'icted with a smoke chamber and a stem socket, a

bowl supported upon and upstaiiding from j said base and having a duct through which it unites with the smoke chamber of the base,;

and a bodyl wall unitedv to and supported from tne top vmargin of the bowl ,and eX-.

tending there'lioinV eownwar'dlyr around the bowl with a substantial,intervening space, and providing a heat radiatingsurtaceot a capacity in excess of the capacity for.' conduction ot heat from the inarginUot the` bowl to said wallgsaid wall beiiigalso united with the base below ,the bottom yot the bowl and being of a substantially spherical forni, withthe base lying adjacent to the pole of the sph'ere whichv is opposite to the mouth of the bowl,the base having a weight relatively'to that of the bowl which ion throws the centerof gravity'of the pipe below its geometrical center and thereby `renders the pipe, self-righting. i

3. VIn a tobacco pipe a base constructed with a smoke chamber and astem-barrel,

a bowl supported upon and upstanding from said baseand having a duct throughA which it` communicates with theI vsmoke chamber of the base, and a body wall surrounding the bowl, with la substantial in-r tervening space; said wall being united to and supported from the topniargin of the bowl and extending therefrom downwardly around the bowl with a substantialintervening space and providing a heat radiating surface of a capacity in excess of the capacity in excess of the conduction of heat from the margin of the bowl to said wall; said wall being also united with theV base below the bottom of the bowl and being of substantially'spherical form; the lower portion of the base being coincidentavithl the lower surface of the spherical body; the stem barrel extending therefrom tangentially to thel sphere of the wall; and the base and its stein barrelconstituting Va Vcounterpoise that renders the pipe self-righting both in a capacity for plane transverse to the axis of the barrel as well as in the planeofsaid axis.
